Abstract

Hydrogen storage is one of the key enabling technologies for the advancement of hydrogen power systems, such as fuel cells, in transportation, stationary, and portable applications. Hydrogen storage/release properties of Mg- and Pd-doped magnesium were studied. The rate of hydrogen release for Pd-doped magnesium hydride was much faster than that for the un-doped magnesium hydride, which is in consistent with that of measured by volumetric method. While the Pd-doped magnesium readily released hydrogen, the un-doped magnesium needed 5 min of incubation time before it released hydrogen. At 10 min, the magnesium hydride and Pd-doped magnesium hydride released 0.76 wt % and 4.03 wt % hydrogen, respectively.
